Electrical Characteristics
Figure 2 shows the undershoot and overshoot voltages at the interfaces of the MPC8555E.
Figure 2. Overshoot/Undershoot Voltage for GVDD/OVDD/LVDD
The MPC8555E core voltage must always be provided at nominal 1.2 V (see Table 2 for actual
recommended core voltage). Voltage to the processor interface I/Os are provided through separate sets of
supply pins and must be provided at the voltages shown in Table 2. The input voltage threshold scales with
respect to the associated I/O supply voltage. OVDD and LVDD based receivers are simple CMOS I/O
circuits and satisfy appropriate LVCMOS type specifications. The DDR SDRAM interface uses a
single-ended differential receiver referenced the externally supplied MVREF signal (nominally set to
GVDD/2) as is appropriate for the SSTL2 electrical signaling standard.
